I told you the car felt crazy fast during the run and now that I am reading the grpahs from 2nd to 3rd gear car was pulling in excess of 1G!!!
As for the drop when I shifted from 4th to 5th there might have been a small slipping invloved or even possibly hitting the limiter for a split second as I was in manual!

How the F were you able to pull 1g at 74 mph? That's amazing!
Were you running any power adders?
What is your peak boost?
